Answer:
The following components shall be used in given order:
1. Step Down Transformer 2. Diode as Rectifier 3. Capacitor
Explanation:
The following components shall be used in given order:
1. Step Down Transformer 2. Diode as Rectifier 3. Capacitor
1.<u>STEP DOWN TRANSFORMER</u>:
The step down transformer is first used to convert the 120 V AC signal into 12 V AC signal. Because the output required is of 12 V.
2.<u>DIODE AS RECTIFIER</u>:
Now, the PN Junction diode is used as a rectifier to convert the 12 V AC signal to 12 V DC signal.
3.<u>CAPACITOR</u>:
Now, the output is in waveforms. So, in order to linearize it in the form of DC current, we use capacitor. The main function of capacitor is to smoothen the signal into a straight line.
A surfer is riding a wave with an amplitude of 6 feet and a period of 24 feet. If the wave completes a period in 8 seconds.The speed of the surfer is 3ft/sec.
A wave's amplitude is defined as its largest displacement on either side of its mean location.
The quantity of oscillations a wave makes in a second is referred to as frequency of wave.
The amount of time it takes to complete one vibration, from A to B, is referred to as time period.
As we know,
ν = λf
where, ν = speed
λ = wavelength
f = frequency
also,
Putting in the values in equation ν = λf gives us,
ν = 24 × ( period of wave must means wavelength of 24ft)
ν = 3ft/sec.
